AST RESEARCH, INC.        TECHNICAL BULLETIN # 1541          10/21/97 
 
 
 
TITLE:  Ascentia P, Slow CD-ROM, MPEG
 
 
ISSUE 
 
   When a user installs the Xing MPEG player on an   Ascentia P and 
   runs the software under Windows 95, the CD-ROM will play very 
   slowly.    

 
BACKGROUND 
 
   The IOS.VXD file in Windows 95 causes excessive seeks on data 
   requests from the CD-ROM drive when playing a video CD.  This 
   results in degradation in the rate of data transfer from the 
   drive.  The computer may seem to stop responding (hang) due to 
   the very slow rate at which the system is reading data from the 
   CD.    

 
ACTION 
 
   To resolve the problem, follow the instructions below:
   
   1. Download the file IOSUPD.EXE from Microsoft's web site
      (located at www.microsoft.com) into a temporary 
      directory.
   
   2. In My Computer or Windows Explorer, double-click the 
      IOSUPD.EXE file downloaded in step 1.
   
   3. Follow the instructions on the screen.    

 
NOTES 
 
   Microsoft updated file IOS.VXD, contained in the IOSUPD.EXE file, 
   to correct the problem stated above.
